The explanations for our butchery are manifold, and sometimes contradictory.

Sometimes we’re a bunch of hipster brats who don’t appreciate the tried-and-true cultural milestones of middle-class adulthood. We spend all our time snapping selfies in our parents’ basements. That means we don’t need cars to get around, nor do we want them. To today’s youngsters, “driving simply doesn’t seem as cool as it once was,” one Fortune magazine article proclaimed.

Or maybe we are venturing out, but when we do, we make more frivolous purchasing decisions than did our forebears. We fritter away our paychecks on avocado toast instead of saving to buy a home.

Or, alternatively, we’re socially conscious, admirably deaf to the siren song of commercialism. Unlike those Material Girls (and Boys) of the 1980s, we think ownership is soul-sucking and pointless. Sharing is caring, bro.

Well, a research paper published last month by economists at the Federal Reserve comes to a different conclusion: Millennials aren’t choosing to break economic traditions. Instead, we’re just broke.

The report, “Are Millennials Different?,” looks at financial and cultural milestones for the cohort born between 1981 and 1997, and how it compares with earlier generations at a similar life stage. Contrary to stereotypes that kids these days have sharply different tastes and aspirations than did kids of yore, the report concludes that “millennials do not appear to have preferences for consumption that differ significantly from those of earlier generations.”

We simply lack the earnings or assets to make those same consumption preferences happen.

It’s true, for instance, that we’re much less likely to own homes. Homeownership rates among young households were close to 50 percent for Gen Xers in 2001 and baby boomers in 1989, the report finds, but only 34 percent for comparably aged millennials in 2016.

Have the scars of the housing bust turned us away from the American dream of homeownership? Survey data suggest otherwise. More likely we’re just still scarred by the Great Recession itself: We simply can’t afford to pursue that dream right now.

After all, many of us entered the job market when employment opportunities were few and far between, and we got stuck on lower-paying career trajectories. The Fed paper finds that millennials, working full time, generally have less income than did either Gen Xers or baby boomers at similar ages.

We also have more student debt than those earlier generations did.

Young adults today are more expected to attend college if they want a decent job — and moreover, to fund that education themselves, given successive rounds of cuts in public dollars to state colleges and universities. Student loan debt in turn can crowd out our ability to borrow for other purchases, such as a house.

After controlling for income, economic and other demographic factors, the researchers found little to no difference between millennials and earlier generational cohorts in their spending on housing, cars and food. In fact, millennials appear to spend more on housing than demographically similarly boomers did. The researchers note that it’s possible our preferences could eventually change, just as the “Great Depression left a lasting impression on the Greatest Generation.” But there’s little evidence that’s happened yet.

For now, what’s odd — and especially unfair — is that millennials are blamed and shamed for “killing” industries that we’ve been effectively shut out of.

We’re not the ones, after all, who bought houses we couldn’t afford and then destroyed the global economy a decade ago.

We’re not the ones who orchestrated a massive disinvestment in public higher education, after the generations before us enrolled for a pittance.

And going forward, we’re not the ones who will benefit from the new $1.9 trillion deficit-financed tax cut, which was effectively an enormous intergenerational transfer of wealth. In case you’re wondering who’s going to pay that back, the answer is millennials, and the generations who come after us — through higher taxes, lower benefits or both. Which is yet another reason for us to pinch every penny we can.
